Megafaunal engineering in the tropical rainforest: African forest elephants (Loxodonta cyclotis) reduce avian species richness but elevate functional diversity

Journal of Animal Ecology, EarlyView.
Our paper investigates the crucial role of African forest elephants (Loxodonta cyclotis) on the functioning of rainforest ecosystems, through the lens of bird communities. It reveals that the critically endangered megaherbivores are inextricably linked to survival of another key group imperilled by land‐use change: understory invertivore birds ...

The morphological affinities of the fossil cranium from Kabua, Kenya Affinités morphologiques du crâne fossile de Kabua (Kenya)

Journal of the Royal Anthropological Institute, EarlyView.
Our current understanding of the origins of Homo sapiens is limited, in part, by the fragmented fossil record from Late Pleistocene and early Holocene Africa. Here, we re‐examine the Kabua 1 cranium, an enigmatic and little‐studied Kenyan fossil discovered in the 1950s. We compare virtual reconstructions created previously by our team with a wide range

Potential Accuracy of Joint Parameter Estimate by Space-Based Radar Altimeter

Известия высших учебных заведений России: Радиоэлектроника, 2017
The subject of research is a space-based radar altimeter. Modern satellite altimeters along with the instant distance to an earth surface are to measure the sea wave height and scattering cross section per unit of a probed spot.

Representation in conservation publishing

Conservation Biology, EarlyView.
Abstract There is a persistent underrepresentation of marginalized voices in academic literature, including that for ecology and conservation. Such exclusion hampers career progression, perpetuating disadvantages for historically marginalized groups in the field, with implications for the direction of conservation research.

Research on Collaborative Optimization of Near-Field ISAC Systems Based on Multi-Waveguide Pinching Antenna Arrays

IEEE Open Journal of the Communications Society
In this paper, a near-field integrated sensing and communication (ISAC) using a multi-waveguide pinching antenna system (PASS) is proposed, where discrete radiating particles are flexibly clamped along multiple dielectric waveguides to realize ...

The stone and the shadow: peasant and aristocratic land appropriation in early medieval Galicia (north‐west Iberia)

Early Medieval Europe, EarlyView.
This paper explores the social dynamics of land appropriation in early medieval Galicia (north‐west Iberia), focusing on the central role labour played in narratives and practices. To that end, it analyses the entire regional corpus of more than one thousand charters dating before 1100, whose distinctive scriptural practices offer exceptional insight ...

Information-Geometric Selection for Validation-Guided Ensembles of Extreme Learning Machines: The LEA-EELM Framework

Mathematics
Extreme learning machines (ELMs) solve output weights in closed form, so an optimized population of ELMs leaves open which members should form the ensemble. We report a controlled comparison of five rules for this selection step inLEA-EELM, where a Lotus

The Fisher-Rao geometry of CES distributions

, 2023
When dealing with a parametric statistical model, a Riemannian manifold can naturally appear by endowing the parameter space with the Fisher information metric.
